UNITED STATES PATENT OFFICE.

HIRAM B. SWARTZ, OF WOOSTER, OHIO.

WINDOW-BLIND.

SPEGIFICATION forming part of Letters Patent No. 472,592, dated April12, 1892.

Application filed September 25, 1891. Serial-N0. 406,878. (No model.)

To all whom it may concern.-

Be it known that I, HIRAM B. SWARTZ, a citizen of the United States,residing at Wooster, in the county of Wayne and State of Ohio, haveinvented a new and useful Window- Blind, of which the following isaspecification.

My invention relates to Window-blinds, and especially to inside slidingblinds, where unusual thinness of blind is required.

It consists of certain details of construction for securing stationaryslats within such blindframe, as hereinafter set forth.

My invent-ion is illustrated by the accompanying drawings, in whichsimilar letters of reference indicate like parts.

Figure 1 is a section of a stile for a sliding blind embodying myinvention. Fig. 2 is a section of a blind, showing stationary slatssecured in position within the adjacent stiles. Fig. 3 is a section ofstile with several stationary slats connected therewith at one end.

In the drawings, A is a section of my improved stile for blinds. It isbored in the usual well-known way, as for rolling slats. It is furtherprovided with longitudinal raised portions 0 along the margin of itsedge adjacent to the slats sufficient to make a shallow depression Balong the edge of the stile to receive the ends of the slats Dand securethem closely together and also prevent them from turning on theirtenons. The slats are made inthe usual way, and the tenons may be roundor square, but should snugly fit the holes in the stile instead ofloosely, as in rolling slats. A furrow e may be out along the edge ofeach slat to admit of closer lap, if desired.

I am aware that pivoted slats inserted in a blind-stile board to receivethe same are old;

also, that the furrow e is not new, and such I do not claim.

My invent-ion consists in the combination of parts shown to provide animproved stationary slat-panel for blinds, so as to have a snug tenonfor each slat, to give additional strength to the blind-frame, and alsoto secure each slat rigidly in horizontal position independently of thenext adjacent slat, so that the series of slats will not dip norcontract or shrink by drying out, as is the case where the stationaryslats are supported by each other by means of a groove in theblind-stile. The novel feature which especially accomplishes theseadvantages is the longitudinal raised portion 0 along one or bothmargins of the stile edge adjacent to the slat-tenons, bearing againstthe outer edges of the slats, and thereby securing them rigidly inplace, while the tenons secure the same horizontally Within theblind-frame.

Having thus described my invention, what I claim is- In a blind-frame,the combination, with the stile A, bored to receive the tenons, of theslats fitted thereto,- said stile further provided with a longitudinalraised portion along the margin of its inner edge to bear against theouter edges of the slats and secure them rigidly in place to form aseries of stationary slats within the blind-frame, substantially asshown and described.

Witness my hand this 1st day of September, A. D. 1891.
